Alex, Have a question:
Does or can the DCA mechanism copy small and even tiny packets during low-level 'igb' device processing? Can IOAT/DCA become involved in moving small packets from the kernel to user-space? For UDP as well as TCP? The reason why we're so interested in the latest 82575 and 82576 chips is the performance improvement potential. We deal with extremely high volumes of 100-200 byte multicast UDP packets which as far as I can tell has not been a major focus for the new DMA controller functionality. My hope is that the second generation of IOAT that includes cache coherent transfers can at some point be applied to our data mix. Large packet off-loading does not help in the slightest.
